Actually, hate to break it you you, but that pattern is textbook ADHD behaviour! I've actually seen many people describe manufacturing themselves crises in order to get things done; here's a typical sample (bold mine):

Sometimes, a person with ADHD can hit the do-or-die deadline and produce lots of high-quality work in a short time. A whole semester of study is crammed into a single night of hyperfocused perfection. Some people with ADHD create crises to generate the adrenaline to get them engaged and functional. The “masters of disasters” handle high-intensity crises with ease, only to fall apart when things become routine again.
